i did do a search sorry i didnt find what i needed...

the car im getting has the 94 ex engine with vtec..its already got an intake..and i think fuel rods...would it be worth while to get a piggyback?? how much will this increase my gas mileage? this kids really smart about his cars..but just doesnt know what the calls are for his engine

 

cheaper and more effective to chip your ecu with crome or uberdata. not only can you adjust fuel mapping but also ign maps, rev limits, launch control........
